Amazon Cloud EC2
Amazon Elastic Compute Cloud (Amazon EC2) is a web
service (AWS) that provides resizable computing capacity—
literally server instances in Amazon's data centers—that you
use to build and host your software systems. With Amazon
EC2, you can get access to infrastructure resources using the
AWS Management Console, API actions, or command line
tools and utilities.

How does Amazon EC2 works
AMI: It Provides templates known as Amazon Machine Images
(AMIs) that contain pre-configured software such as an operating
system, application server, and applications. You use these
templates to launch your server instances. After you launch your
instance, you can use it just like a physical server
Replicate existing AMI: You can also launch multiple instances of
an AMI, thus replicating the same configuration across each of the
instances
Customized AMIs: In addition, members of the AWS developer
community have published their own custom Windows AMIs
Customize your own AMI: you can simply customize the resulting
Windows instances to provide the data or software you need each
time you launch an instance
